Х-1ое число
У-2ое число
Х+У=Х-20
Х+У=У-34
Х-20-У+34=0
Х=У-14
У-14+У=У-14-20
У=-20
Х=-34
Сумма -54

ДАЮ 100 БАЛЛОВ! Помогите, пожалуйста(
Нужно поставить 5 вопросов к тесту и выписать все сказуемые , определить временные формы и указать инфинитив.
1.What is so special about Oxford and Cambridge, the two oldest universities in England? Why do so many students want to study there?
2.Both of these university towns are very beautiful. They have some of the finest architecture in Britain. Some of their colleges and libraries are three, four and even five hundred years old, and are full of valuable books and precious paintings. Both towns have many lovely gardens, where the students can read and relax in the summer months.
3.Oxford is the older university of the two. The first of its colleges was founded in 1249. The university now has thirty-four colleges and about twelve thousand students, many of them from other countries. Oxford is, of course, famous for its first class education as well as its beautiful buildings. Some of the most intelligent men and women in the country live and work here. Oxford gives them what they need: a quiet atmosphere, friendly colleagues, and the four-hundred-year-old Bodleian library, which has about five million books.
4.It is not easy to get a place at Oxford University to study for a degree. But outside the university there are many smaller private colleges which offer less difficult courses and where it is easy to enroll. Many students in these private schools take business, secretarial or English language courses.
